foregoing construction the cylindrical valve 2i is protected from the wear of the piston which travels in the inner cylinder 60, While at the same time it is, kept cool by the Water jacket 14 and that it is driven from .its lower end in close proximity to the crank shaft of the engine7 much simpler mechanism being therefore required than Were this cylindrical valve driven from the top of the engine as is shown in my above 1nentioned application, While as shown in Fig. l the inner cylinder' extends sntliciently below the Water jacket to bear upon thebase support l() in any 'suitable sort ot' joint 62, thereby steadying this end of the cylinder against; any motionsof the pistonn It will also be noticed that by removing the bolts 20 the entire inner cylinder may be removed for repairs and replacement 'Without disturbing the other parts.

In Fig. 2 is'shown a modified form of structure with a reduced size combustion chamber b4- carrying its own closed end. 6G, all as more fully shown, described, and claimed in the above mentioned prior ap plication. In this case the cylinder (38 also rests upon. the hase 1.0 in a joint 70. l

Having thus described my invention what VI claim as new and desire to ters Patent isl. In a device of the class described, in combination with a base, a cylinder secured to said base, a second cylinder inside the first cylinder, spaced apart from it to form an annular recess betweenl the two cylinders,

a Valve in said recess, means connecting the end of the inner cylinder to the base memi ber, means connecting the opposite end of said cylinder to the outer eyln'uler, and

means located within a space formed between a portion of the end ot the outer cylinder, a portion of the end of the inner cylinder and the base member for driving said valve.

2. ln a device of the clase described, in combination with a hase member, anouter cylinder secured to and rising trom the base men'iher, an inner cylinder smaller than the outer 'cylinder adapted to be inserted through the outer cylinder' into secure by Letv Loenen' engagement with a guiding support on.

the inner cylinder fitting over the upper end of the outer cylinder, means securing said flanged head to the outer cylinder, and a rotatable cylindrical Valve member in an annular space formed between said two cylinders. y

In a device of the class describ'l, in combination with a base member, anoutcr cylinder secured to and rising from the base member, an inner cylinder smaller and longer than (he outer cylinder adapted to be inserted througl'l the outer cylinder into engagement with. a guiding rejection on the base, a flanged head on tie u )per end of the inner cylinder fitting over tlle upper end et' the outer cylinder, means securing said flanged head to the outer cylinder, a rotatable cylindrical Valve in the annular space formed between said two cylinders` adapted to control ports for the admission and exhaust of gas to the inner cylinder, and means for rotating said 'valve member.

Al. In a device of the class described, in combination with a base member, an outer cylinder secured to and rising from the base member, an inner cylinder smaller and longer than the outer cylinder adapted to be inserted through the outer cylin'iler into engagement with a guiding projection on the base, a flanged head on the upper end ol the inner cylinder fitting over the end of the outer cylinder, means securing said flanged head to the outer cylinder, a rotatable cylindrical valve member in the annular space forn'ied betweei said two cylilr ders adapted to control entrance and ef hanst ports leading into the inner cylinder and means located immediately adjacent to the hase and adjacent to the lower end of the inner cylinder for rotating' said valve member. l

In witness whercolr have hereunto subscribed my name inthe presence of two witnesses.
